REDDLE.

Application tiled September To all wiwm it may concern Be it known thatI, GREILET N. Comma, a citizen or the United States, and a resident ofNarberth, in the county of Montgomery and State of Pennsylvania haveinvented an Improvement in Riddles, of which the following is aspecification.

My invention relates to riddles and has for its general object toprovide a simple but novel and improved construction of riddle which isadapted for the screening of clay, color, casein, pulp, glue or otherviscous or semi-liquid materials which are more or less diflicult tohandle.

A further and more specific object of the invention is to provide ariddle which is adapted to effect screening of semi-liquid or viscousmaterials, such as pulp employed in the manufacture of paper, for thepurpose of removing therefrom lumps and particles of various kindsduring an upward flow of the material, whereby the said lumps or otherparticles are caught upon the lower side of the screen and are thereforeapt to descend therefrom and thus prevent clogging of the screen.

A still further object of the invention is to provide a novelconstruction of riddle wherein the semi-liquid or viscous material to bescreened is delivered to a chamber underneath a screen extending acrossthe said chamber and is caused to flow upwardly gravity acting uponlumps or particles which are too large topass through the screen causesthe same to descend from the said screen to thereby prevent clogging ofthe same.

A further object of the invention is to provide a riddle with a novelconstruction of screening apparatus having means whereby such lumps andparticles as may be separated ifrom the material being screened may beremoved readily without the necessity of dismantling the structure.

To these and other ends my invention comprehends the construction andarrangement of parts as hereinafter described in the specification,particularly pointed out in the claims and as illustrated in theaccompanying drawing forming a part of this specification and in whichis illustrated one form of embodiment of the invention. However, it willbe understood that the invention is susceptible of embodiment in otherforms of construction than that shown and that changes in the details ofconstruc- 8, 1922. serial Ho. 5%3533.

tion may be made within the scope of the claims without departing fromthe said invention. I,

In the drawing:

Fig. 1 is a view in side elevation of a riddle embodying my invention;

Fig. 2 IS a view in side elevation of the screening portion of thestructure, which s talcen at right angles to the view shown in 1g. 15

F1g. 3 1s a vertical longitudinal sectional view taken on the line 3-3of Fig. 4; and Fig. 4 IS a view in top plan of the portion of thestructure shown in Figs. 2 and 3.

Referring to the drawing: 1 and 2 designate the o posite side members ofthe frame of 'a ridd e structure to the upper ends of which s secured anelectric motor 3 by means of brackets 4: which project laterally fromsaid motor and the outer ends of which are secured to the said sideframe members 1 and 2 at points adjacent the upper ends of the latter. Abail-like member 5 is pivotally secured to the upper end portions of thesaid side members 1 and 2 by means of bolts 6. The sald side members arealso connected at a point intermediate their ends by means of a bar 8having a bearing 9 at its center in WhlCh is journaled the lower endportion of a shaft 10 coupled at 11 to the motor shaft 12. An unbalanceddisk 13 is secured to the lower end of the shaft 10 and rotatestherewith.

The foregoing construction as described is similar to that disclosed inFig. 1 of Letters Patent of the United States, No. 1,- 152,396, datedSeptember 7, 1915,the unbalanced disk 13 corresponding with theunbalancing member22 of the said patent.

The lower ends of the side frame members 1 and 2 are connected atdiametrically opposed points, as indicated, to the upper edge portion ofa screening chamber or receptacle 20. For the purpose of rendering theconnection between the lower ends of the said members 1 and 2 and thesaid chamber or receptacle 20 more rigid, I have provided the bracingmembers 21 having laterally extending portions which are secured to thechamber at points adjacent the lower ends of the members 1 and 2 andalso to the said members.

The screening chamber 20 comprises an closed by ,a removable cap or plug23, as shown. A. screen 25, of any suitable desired construction, issituatedwlthin and extends across the cylindrical portion of the chamberor receptacle 20. The sald screen is situated in a plane a shortdistance above the lower end of the cylindrical portion of the saidchamber or receptacle as shown, and is conneted to the said portion bymeans of circular or annular angle plates 26 and 27. The outer edge ofthe screen is situated between the horizontal inwardly extending flangesof the said angle plates and is secured thereto by means of screws 28.The lowermost of the angle plates 27 may be secured to the cylindricalportion of the chamber or receptacle in any suitable manner, as bysoldering or spot welding, but the upper one of the said angle platesshould not be permanently secured to the said chamber, but is held inposition by the screws 28 by means of which the screen is held in place.

The outer edge of the screen may be secured to the said chamber in anyother suitable manner desired.

For the purpose of introducing semiliquid or viscous material into thechamber underneath the screen l have provided funnel 30 secured to andsupported upon the upper end of a pipe 31 which is secured to the saidchamber and communicates with the interior thereof through a port 32 asshown. The material entering the chamber underneath the screen 25 iscaused to flow upwardly through the said screen and is dischar ed fromthe said chamber through the disc arge pipe 33 connected to the saidchamber at a point a distance above the screen, as shown.

In the use of the riddle it will be understood that it is suspended bymeans of a hook or otherwise which engages the bail 5 and while sosuspended the electric motor 3 is operated to {lactate the unbalanceddisk 13. The rotatioiiiof the latter causes gyratory movement of thestructure,creating a centrifugal force which supplements the force ofgravity to cause the material to flow from the funnel or hopper 30through the pipe 31 into the chamber 20 underneath the screen 25. Thelevel of material within the funnel 30 and pipe 31 must be kept at aheight above the plane of the discharge port leading into the dischargepipe 33.v

By reason of the fact that the level of the material within the funnel30 and pipe 31 is hi her than the level of a plane through the ex austport which communicates with the discharge'pipe 33 the semi-liquid orviscous material is caused to flow upwardly throu h the said screen andout through the said (115- aseaeai ortion 22 by rethe said movaltherefrom of the c osure 23. lit will be apparent, therefore, that thesaid lum s or hard articles may be removed .readi y without ismantlingthe machine.

Having thus described myinvention, what ll claim and desire to secure byLetters Patent is:

1. In a gyrator riddle, the combination of a receptacle at t e lower endof the riddle structure, a screen extending across the said receptaclein a plane intermediate the opposlte ends thereof, means for deliveringa iquid to be screened to the said receptacle at a point below the saidscreen, and a discharge conduit having connection with the saidreceptacle at a. point above the said screen.

, 2. In a riddle, the combination of a frame, a receptacle supportedupon the lower end of said frame means carried by the said frame for edthereof and of the said receptacle, a screen extending across the saidreceptacle in a plane intermediate its ends, and means for causing aliquid to be screened to flow from a lower to a higher level within thesaid receptacle, the said liquid flowing through the said screen.

3. lln a riddle, the combination of a frame, a receptacle secured to thelower end thereof, means carried upon said frame for effecting gyratory'motion thereof and of the said receptacle, the said receptaclecomprising a cylindrical upper portion and an inverted truncatedcone-shaped lower portion, a screen extending across the said receptaclein plane a distance above the lower end of the cylindrical portionthereof, a funnel situated upon the outside of the said receptaclehaving connection therewith. below the said screen, and a discharge pipehaving connection with the said receptacle at a point above the saidscreen but below the said funnel, substantially as described.

In testimony. that I claim the foregoing as my invention, lI-havehereunto signed my name this 5th day of September, A. D,

GRlELLlET N. COLLINS.
